Winds and Accretion in Young Stars
Suzan Edwards
Establishing the origin of accretion powered winds from forming stars is critical for understanding angular momentum evolution in the star-disk interaction region. Here, the high v…
Redshifted Absorption at He I 10830 as a Probe of the Accretion Geometry of T Tauri Stars
William Fischer, John Kwan, Suzan Edwards +1
We probe the geometry of magnetospheric accretion in classical T Tauri stars by modeling red absorption at He I 10830 via scattering of the stellar and veiling continua. Under the…
Modeling T Tauri Winds from He I 10830 Profiles
John Kwan, Suzan Edwards, William Fischer
The high opacity of He I 10830 makes it an exceptionally sensitive probe of the inner wind geometry of accreting T Tauri stars. In this line blueshifted absorption below the contin…
Probing T Tauri Accretion and Outflow with 1 Micron Spectroscopy
Suzan Edwards, William Fischer, Lynne Hillenbrand +1
In a high dispersion 1 micron survey of 39 classical T Tauri stars veiling is detected in 80%, and He I 10830 and Pgamma line emission in 97% of the stars. On average, the 1 micron…
He I 10830 as a Probe of Winds in Accreting Young Stars
S. Edwards, W. Fischer, J. Kwan +2
He I 10830 profiles acquired with Keck's NIRSPEC for 6 young low mass stars with high disk accretion rates (AS 353A, DG Tau, DL Tau, DR Tau, HL Tau and SVS 13) provide new insight…
Near-Infrared Classification Spectroscopy: J-Band Spectra of Fundamental MK Standards
Lloyd Wallace, Michael R. Meyer, Kenneth Hinkle +1
We present a catalog of J-band spectra for 88 fundamental MK standard stars observed at a resolving power of R ~ 3000. This contribution serves as a companion atlas to the K-band s…
Near-Infrared Classification Spectroscopy: H-band Spectra of Fundamental MK Standards
Michael R. Meyer, Suzan Edwards, Kenneth H. Hinkle +1
We present a catalogue of H-band spectra for 85 stars of approximately solar abundance observed at a resolving power of 3000 with the KPNO Mayall 4m FTS. The atlas covers spectral…
